burkert 000239092，burkert 2871，宝德防爆比例阀，宝德2875调节阀，burkert 2873。手动平衡阀和自力式平衡阀，它们都是温控阀或电动调节阀的辅助流量调节装置，但又是非常重要的，如果选型不当，或设计不合理，电动调节阀或温控阀都不能很好工作。

In continuous fl ow applications, the choice of an appropriate valve size is much more important than with on/off valves. The optimum size should be selected such that the resulting fl ow in the system is not unnecessarily reduced by the valve. However, a suffi cient part of the pressure drop should be taken across the valve even when it is fully opened.Recommended value: Δpvalve > 25 % of total pressure drop within the system Otherwise, the ideal, linear valve curve characteristic is changed.If the differential pressure (difference between inlet and outlet pressure) exceeds half the value of the nominal pressure, the characteristics may change.For that reason take advantage of Bürkert competent engineering services during the planning phase!
